Security readout for executives and security teams
Plain-English summary
CVE-2026-24390 affects the WordPress Kentha Elementor Widgets plugin before version 3.1. A logged-in attacker may be able to make the plugin include unintended local PHP files, potentially exposing data, changing site behavior, or disrupting service. Sites not using this plugin are not exposed based on the provided sources.
Executive priority
Treat as a high-priority WordPress plugin update for sites using Kentha Elementor Widgets. Business urgency is highest where many users can log in, public registration is enabled, or the affected site handles sensitive data. No active exploitation is confirmed in the supplied sources.
Technical view
The issue is classified as CWE-98: improper control of a filename used in a PHP include/require statement. The CVSS 3.1 score is 7.5 high, with network access, high attack complexity, low privileges required, and high confidentiality, integrity, and availability impact. Sources describe local file inclusion in kentha-elementor versions below 3.1.
Likely exposure
Exposure is likely limited to WordPress installations running QantumThemes Kentha Elementor Widgets / kentha-elementor below 3.1. The CVSS vector indicates exploitation requires an authenticated low-privilege user, no user interaction, and network reachability.
Exploitation context
The provided data does not show CISA KEV listing or active exploitation. Patchstack has a vulnerability database entry, but the source bundle does not include exploit availability, exploitation evidence, or detailed attack prerequisites beyond the CVSS vector.
Researcher notes
Source details are limited. The description mentions PHP remote file inclusion terminology while also stating local file inclusion. The CVSS vector requires low privileges and high attack complexity. The affected range is described as through versions below 3.1; verify exact fixed version with vendor or Patchstack before closing remediation.
Mitigation direction
- Identify all WordPress sites using Kentha Elementor Widgets / kentha-elementor.
- Update the plugin to version 3.1 or later if available from trusted vendor sources.
- If immediate update is unavailable, restrict access to authenticated accounts and remove unnecessary low-privilege users.
- Monitor vendor and Patchstack guidance for confirmed remediation details.
Validation and detection
- Check installed plugin name and version across WordPress environments.
- Confirm affected instances are below version 3.1.
- Review WordPress and web server logs for unusual file-include or PHP errors.
- Verify no unexpected administrator users or plugin/theme file changes exist.
